Race is a modern concept that emerged during European colonization and the slave trade. Initially based on physical differences, it evolved into pseudoscientific theories used to justify oppression. These historical constructions continue to shape contemporary understandings of race and racism. Racial formation theory challenges the idea of race as biological, emphasizing its social construction. It explores how racial categories are created, transformed, and destroyed through social, political, and economic forces. This process involves both micro-level interactions and macro-level institutions and ideologies.
